3 USACE / NAVFAC / AFCEC / NASA UFGS (August 2016) Preparing Activity: USACE Superseding UFGS (August 2010) UNIFIED FACILITIES GUIDE SPECIFICATIONS References are in agreement with UMRL dated January 2018 SECTION WOOD STRIP AND PLANK FLOORING 08/16 NOTE: This guide specification covers the requirements for wood strip and plank flooring for gymnasiums, handball and squash courts, and other special purpose applications. Adhere to UFC Unified Facilities Guide Specifications (UFGS) Format Standard when editing this guide specification or preparing new project specification sections. Edit this guide specification for project specific requirements by adding, deleting, or revising text. For bracketed items, choose applicable item(s) or insert appropriate information. Remove information and requirements not required in respective project, whether or not brackets are present. Comments, suggestions and recommended changes for this guide specification are welcome and should be submitted as a Criteria Change Request (CCR). PART 1 GENERAL 1.1 SUMMARY NOTE: Wood strip flooring is very sensitive to ambient humidity conditions since all wood flooring will expand and contract as relative humidity varies. In order to keep the flooring manufacturer's warranty valid after installation, the areas in which the wood floors are installed must be adequately ventilated with natural or mechanical air circulation at all times during the life of the flooring. If prior experience at the site indicates that SECTION Page 3

4 relative humidity during sustained heating periods will fall below 35 percent, the office in charge of building maintenance should provide equipment to introduce moisture into the floored area when required; conversely, if relative humidity increases to 50 percent or higher at any time, measures should be taken to dry the floored area, including turning on the heat. At sites with humidity problems, the maintenance of the flooring may require: 1) The design of a localized HVAC system to also react to and automatically control ambient humidity conditions through the life of the flooring; or 2) Continuous monitoring of relative humidity with on the spot corrective actions, as needed, without altering the HVAC system. These alternatives could be very expensive or impractical. The designer, in the absence of local experience, should coordinate with local manufacturers to specify compatible floorings which have performed well locally; that is, the designer should check gymnasiums in the area when building a gymnasium floor; the same for handball courts, etc. Of course, the designer has the option of purchasing commercially available floating or sleeper systems specifically designed to reduce the possibility of buckling and cupping brought on by moisture buildup or specifying other types of flooring when a cost analysis (including all HVAC variations) indicates that wood strip flooring is not economical. This specification is written to allow the Contractor to build wood strip floorings for gymnasiums, handball and squash courts, and other special purpose applications but does not preclude the installation of competitive, manufacturer standard, integrated systems. 1.2 REFERENCES NOTE: This paragraph is used to list the publications cited in the text of the guide specification. The publications are referred to in the text by basic designation only and listed in this paragraph by organization, designation, date, and title. Use the Reference Wizard's Check Reference feature when you add a Reference Identifier (RID) outside of the Section's Reference Article to automatically place the reference in the Reference Article.

The Guide Specification technical editors have designated those items that require Government approval, due to their complexity or criticality, with a "G." Generally, other submittal items can be reviewed by the Contractor's Quality Control System. Only add a G to an item, if the submittal is sufficiently important or complex in context of the project. For submittals requiring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following the "G" designation to indicate the approving authority. Codes for Army projects using the Resident Management System (RMS) are: "AE" for Architect-Engineer; "DO" for District Office (Engineering Division or other organization in the District Office); "AO" for Area Office; "RO" for Resident Office; and "PO" for Project Office. Codes following the "G" typically are not used for Navy projects. Use the "S" classification only in SD-11 Closeout Submittals. The "S" following a submittal item indicates that the submittal is required for the Sustainability enotebook to fulfill federally mandated sustainable requirements in accordance with Section SUSTAINABILITY REPORTING. Choose the first bracketed item for Navy, Air Force and NASA projects, or choose the second bracketed item for Army projects. SECTION Page 6

The slab must be depressed as required by the floor specified. 3.2 INSTALLATION Install flooring in accordance with the approved installation instructions of the manufacturer. Submit manufacturer's descriptive data and installation instructions. Wood nailers are specified in Section ROUGH CARPENTRY. Unless otherwise approved, flooring must be laid parallel to the length of the area to be floored. Strips must be laid [with close joints, snugly driven up but providing for absorption of a small amount of expansion] [to allow for intermediate expansion in accordance with humidity SECTION Page 13
